' UNITED STATES PATENT oFFlcE 6 Claims.

The essential object of the invention is to provide an incinerator in which waste material may be burned at all times with safety.

A further object of the invention is to provide an incinerator in which the material vto be burned may conveniently be stirred to facilitate combustion; and, also, to provide an incinerator from which the ash may be easily removed.

The invention canbest be seen and understood by reference to the drawings, in which Fig. 1 is a perspectiveof the incinerator.

Fig. 2 is a front elevation with the incinerator in open inoperative position for cleaning the grate.

Fig. 3 is a vertical section of a portion incinerator; and

Fig. 4 is a plan taken on the line 4-4 of Fig. 3.

Referring to the drawings I represents the body of the incinerator. 'Ihis body is made of sheet metal, cylindrical in form, and imperforate.

of the The body is provided with handles2 by which which functions, also, as a base support. This holder is composed of strips of Sheet metal. Of these 6 represents vertical spaced strips circularly arranged to assist in the formation of theframe which embraces the lower portion of the incinerator body. ylilhcircling these strips, and riveted to them, are spaced hoops, or bands, l. Certain of the strips 6 of those oppositely arranged are extended downwardly below the bottom hoop 'I of the holder and bent upon themselves to provide legs 9 which support the holder, and thence are bent to provide sections I0 ,which extend horizontally and .diametrically, crossing one another to form the open bottom of the holder, the strip sections I0 being riveted to one another at the' point of their crossing. With 5() their ends fitting within those turned portions of the strips which form the legs 9 of the holder, and rising upwardly therefrom, are bent pieces I2, bent to provide lifts, or supports, I3 on which the grate, fitting loosely withinthe holder, rests. v

After providing the lifts, or supports,l for the grate the pieces I2 are bent down and riveted tothe sections Ill of the strips.

The grate resting upon the lifts I3, and fitting loosely Within the holder, is a movable grate and, accordingly, may be shaken, for which purpose the grate is provided with a shaker I5. This shaker is riveted to the under side of the grate and its shank projects laterally betweenl a set of the spaced bars 6 of the holder, and is tted with a handle |51. The shaker is movable through the arc lying between the spaced strips 6 between which the shank of the shaker is extending. The arrangement is, alsopreferably such that during the shaking the shank of the shaker may move over the top edge of the lower band `'I ,over which the shank is projecting, the yrising of the lifts I 3 which support the grate being such 'as will locate the grate in position slightly above the top edge of the lower hoop I on the holder so as to permit the shank of.y the shaker resting on the hoop during the shaking.

The body I of the incinerator may rest upon the grate but, if resting upon the grate thebody will be moved during the shaking and this is avoided by providing a separate support for lthe body. To vthis end. the vertical strips 6 of the holder are provided on theinside with a circular band, or hoopv I6 riveted thereto. Encircling the lower end of the body I is a band, or hoop I1, riveted thereto. body is so locatedwith relation to the hoop I6 on the holder that when the body is lowered into the holder the band I'I on the body will engage theband I6 yon the holder, and the body willy be supported from off the shoulder on the holder thus provided. When thus supported the bottom end of the b'ody will just clear the grate and permitlof the grate being moved without moving l the body. The grate is preferably provided with an upturned flange I8 around its peripheral edge which overlaps the bottom edge of the body I when resting in the holder in order to form at this point a relatively tight joint. The grate is, also, provided with angle pieces I9 xed to the top surface thereof ywhich act as stirrers for the l material being burned when the grate is shaken or moved.y

The'body I of the incinerator is provided with a cover 2li having a flanged edge 2| which laps by the top of the body when the cover is closed. The cover is preferably a hinged cover, hinged to the bodyby hinge connection 22. On the side of thecover opposite its hinged connection is a handle 23 for opening the cover. The'hinged The band, or hoop I1, on the `Mounted on the top of the conical wire mesh 21 is a guard 28. This guard is concaved, is separated from the opening in the cover by the conical wire mesh, and is preferably slightly larger than the opening 26 in the cover. The conical wire mesh is secured to the cover `and reinforced by metal straps 29 riveted to the cover and crossing one another in the -apeX of the screen. 'Ihe guard 28 is secured to these straps at the point where they cross by means of a bolt land nut connection 30.

The general operation is as follows: Assuming the body of the incineratorA whichforms the combustion chamber to beset within the holder -and the cover closed, combustion `of material within the incinerator will be carried von with practically absolute safety under all conditions. The flame will be 'confined to the incinerator and will not even lap through the screened opening in the cover. There will be little or no escape of sparks, and lshould any sparks pass through the mesh they will strike the guard and bedeflected back onto the cover.' Air will be admitted for purposes of combustionthrough the openings in the grate although more or less air will enter around the edge of the grate between it and the bottom edge of the incinerator body. To facilitate combustion within the incinerator in case it becomes logy the grate may be shaken, 'at which time the angle pieces on the grate will act as stirrersto the material being burned.-

After the combustion has been completed the body may be lifted out ofthe holder and the ash on the grate then swept away or allowed vto be removed by the wind. In fact, it is not necessary to remove the body of the incinerator from the holder for clearing the grate. The Ybody only need be lifted sufficiently to provide access to the grate for cleaning it, orfor thewind Vto blow the ash away. For holding the body when lifted the top band lof the holder has pivoted to it a hook 3l having a handle 32. The normal gravitated position of this hook is one in which the hook will lie within the plane of the body. Accordingly, when the body is in place inthe holder the hook will bear against the side of the body. .When, however, the body has been raised in the holder to a point Where the bottom edge of the body will lie above the hook, then the hook will move forward into the plane of the body beneath its bottom edge and on again lowering the body into theV holder the hook Will hold the body in an elevated position where it may be left for clearing of the grate. When it is again desired to use the incinerator the hook is released by upward pull upon its handle, when the body will fall back into place and the incinerator will be ready for use.
